Golf’s GOAT, had a Rolex Sea-Dweller Deepsea D-Blue on his wrist the day he conquered the final round to win the game’s most iconic match. Join us on a journey of what is under the cover of the Rolex Sea-Dweller Deepsea models that makes it special enough to be chosen by a sports legend.

Rolex Sea-Dweller Deepsea History

The Rolex Sea-Dweller is a line of ultra-resistant diver’s watches, originally engineered for deep-sea exploration to a depth of 2,000 feet and today rated for 12,800 feet for the Deepsea model. These watches were specifically designed for professional divers as tool watches to use for safe underwater operations. Originally developed in 1967, the original Rolex Sea-Dweller became available to the public in 1971.

In 2008, Rolex introduced the Deepsea variant of the Sea-Dweller model, which had an official depth rating of 12,800 feet. The size of the watch is considerable, at a 44mm case diameter, but this is fashionable in spite of the fact that the large surface area is necessary to keep the watch from being damaged by water pressure at such a depth. The Rolex Sea-Dweller Deepsea also features a Ringlock system that seals the crystal onto the case as well as a diver’s extension link for the bracelet clasp.

This Watch Goes Deep

To accommodate such extreme depths, several features of the watch have been engineered for specific needs under water. The sapphire crystal is 5.5mm thick to withstand intense pressure under the sea. The screw-down Triplock winding crown, developed and patented by Rolex, ensures that no error can be made in the watch’s ability to tell time, which is a safety concern when on a limited supply of oxygen. Additionally, the specially patented helium release valve developed by Rolex enables excess pressure that builds up in the watch case to escape during the decompression phase that saturation divers go through.

Movement

The Rolex in-house Caliber 3235 self-winding movement is incorporated into the Deepsea. The 3235 incorporates magnetism-resistant nickel phosphorous, making the movement extremely durable and reliable as well as highly efficient. The hairspring is made of Parachrom, according to Rolex, which is used for better shock resistance for improved precision over ordinary hairsprings. Like all of Rolex’s in-house movements, the 3235 has run a gauntlet of tests even more stringent than COSC certifications that most manufacturers use. In short, the Deepsea is precise within -2/+2 seconds per day.

 

Appearance

The entire watch is made of corrosion-resistant material such as titanium and ceramic. The rotating bezel on the Rolex Sea-Dweller Deepsea is scratchproof and fade proof using Rolex’s specifically patented processes. The bezel also features a knurled edge, which makes it easy to grip for a diver wearing thick gloves. The large case diameter at 44mm and thickness of almost 18mm makes the Deepsea comfortably worn by medium to large wrists.

The Rolex Sea-Dweller Deepsea D-blue dial is graduated from deep blue at the top to black at the bottom, a unique element incorporated in 2014 and continuing on today’s models. The hands and hour markers are made of white gold for a touch of luxury amid all this rugged construction. Due to the extreme pressure, the watch can withstand, the “Cyclops” lens over the date window is not present on the Deepsea variant of the Sea-Dweller line.

Special Editions

Released in 2012, the Rolex Deepsea D-Blue,  as seen on Tiger Woods, was actually brought to life to commemorate James Cameron’s solo dive to the bottom of the Mariana Trench, a jaw-dropping 36,000 feet deep.

Making the decision to get a Rolex Sea-Dweller or spring for the Deepsea variant depends on your budget and your sense of adventure. Both are engineered for flawless operation in the harshest conditions, so if you need a diver’s watch ready to stand the test of time, you cannot miss in choosing Rolex Sea-Dweller or the amped-up Deepsea.
